Alkaline earth metals are group two of the periodic table. They consist of:
Berryllium Be
Strontium Sr
Magnesium Mg
Barium Ba
Calcium Ca
Radium Ra
All of the members of the Alkaline Earth Metals are solids. Most of these metals are shiny, and fairly soft. The color of the Alkaline Earth Metals is generally white or a shade of silver. A physical property is the ability to change color when exposed to a flame. For example, magnesium will turn to a very light white, calcium will turn a darker shade of red, and strontium will turn a very bright red.
Every metal in this group, except for beryllium, have the chemical property of being able to give off oxides when exposed to room temperature. This process makes the metal dull. When exposed to water these metals tend to give off hydrogen. These metals have a positive charge at +2 because there are a lack of electrons. This makes it bond more easily with other elements.
An interesting fact about Alkaline Earth Metals is that they remain a solid even when they are inside of a fire.
These elements are commonly found in several different substances. For instance, beryllium is commonly found in emeralds. Magnesium is found in many frequently found rocks such as talc and mica. Calcium is found in many drinks such as milk and orange juice.
Calcium is very important to he human body. It helps strengthen and repair bones.
